Hi David, I used the latest qemu code (commit id: 4e71220387e88a22) and kernel (v4.5) to test the post-copy, and find the guest get crashed after live migration, no matter I did a local live migration or live migration between two hosts. I just ran the stress as the workload in guest. It seems the post-copy is broken?
Stress parameters: stress --vm 2 --vm-hang 1 --vm-bytes 2048M --vm-keep QEMU parameters: ./qemu-system-x86_64 --enable-kvm -smp 4 -m 8192 -monitor stdio -drive file=/share/centos6u6.qcow Liang
